Sens. Bill Cassidy of Louisiana and Kyrsten Sinema of Arizona bridged a political divide on Tuesday by introducing the first bipartisan paid parental leave idea.

The proposal leverages a portion of the Republican tax overhaul to let parents pay for childcare or time off work. The tax bill President Trump signed into law in 2017 increased the Child Tax Credit from $1,000 to $2,000 per year, a portion of which Sinema and Cassidy want new parents to be able to take early to help fund childcare or lost wages.
